    Someone needs to run their truck out of fuel and see how much it takes to fill the tank so we can put this to bed.

    I just drove from Houston to Harrisburg, PA … only had to fill twice. Low fuel light came on at about 560 miles just past Meridian, MS and took a little over 32G. I forget where the second fill was, it’s all a blur. Very happy to average 17.5mpg traveling 70-75mph.

    Can hit 20mpg from Houston to hill country with a tail wind, but more realistically 18.5.

    It is nice with city driving that I only have to fill up once a month. My commute to work is 6.2 miles and get 12-14 depending if I want miles or smiles per gallon.

    Sorry for the late reply, been kind of MIA around here.
    Costco gas has the same requirement as the warehouse. You need to use Visa unless it’s a debit card then Mastercard is ok. I’m not sure about Amex but I don’t think they accept them.

    I want to know what I’m doing to not get this kind of fuel economy on highway travel. Max I’ve ever gotten is just under 17, long range drive, cruise, all highway.

    Do you have hills in your area? If so, it's probably the cruise control.

    Total elevation changes under 200. Almost pancake flat.

    That was only over a 46 mile distance, so my guess is it was pretty flat ground, mild temperatures, and just cruising 55-60 with very few stops, if any. I average 15.5-17 driving 4 hrs across hills 65-75mph going up to camp.

    Just got back from camp perry Ohio where my daughter participated in the CMP air rifle championships. From Maryland to Ohio and back I averaged 17.2 mpg which I thought was pretty darn good. The fillups were still shocking to my wallet but the truck was very comfortable throughout the trip.

    We just took our Tundra on a 600 mile round trip road trip. Most of the time I was driving at about 75 mph. Total mileage ended up at 16.0 mpg. That included a mountain pass and several substantial inclines, but also some good downhills and flat lands. I was plenty happy with 16 because the truck was so dang comfortable. All four of us had plenty of room, the truck was smooth and powerful, and we arrived at our destination feeling good. It's like paying extra for first class. :D

    I just did a 5200 mile trip for the second half of July. Averaged 14.5mpg (calculated off fuel used and actual distance traveled) fully loaded with tools, gear, rack, tent, etc. 3/2 lift on 35s. Mostly highway but mixed in offroad, exploring , and some in town use as well. Usually showed empty and took 30gal to tip off.

    Oddly my gas light never turns on until maybe 7 calculated miles left on the tank.

    Someone suggested running a 38 gallon Tundra out of fuel to confirm the capacity. I did just that within the first month of ownership. I made the calculation that the tank was clean enough to make the risk manageable. When the range counter reached zero, I zeroed out my trip A odometer and kept driving (City driving) until the truck died. Of course, I had a 5 gallon gas can in the bed. What I found is that I drove 93 city miles past zero range. I then added the 5 gallon gas jug and drove to a gas station where I filled with 32 gallons of gas.

    Yes. It's in the textbooks at every auto mechanic school.

    Any SAE or factory certified mechanic will confirm this.

    Tire size? Lift? No reason your Tundra shouldn't be close to 19mpg or better all the time in your conditions. Mine would...

    Just drove from Roseville CA to Ashland OR…about 320 miles and only avg about 15. I have the small tank and this is about my max without going too far into the “refuel light” zone reserve with highway miles. Hate the constant refueling and looking to go 38 soon if i can get one in CA. I do have a heavy foot though.

    Pedal commander got me 18.1 on the way to the mountains and 20.1 on the way back. It's eco mode is worth the price of it. And training yourself to drive like pops is certainly part of it. It'll cure a lead foot if that's what your goal is.

    I'd look into the Costco Citi card: 1) it counts as your membership; 2) you get 3% fuel back - we got one just for fueling and found it to be one of the better cost back options for fuel

    another perfect example of useable vs capacity are motorcycle tanks - especially when they straddle the frame. The fuel line comes out of one side of the tank (left or right) and the other side will always hold onto some fuel that will not be able to drain over to the other side of the tank. I'm just happy to have 32 gals vs 20 or less with my avg 13 mpg :spending:

    4% cash back on gas for the first $7k, I believe 1% cash back after
    3% cash back on travel
    2% cash back on Costco purchases
    1% cash back on everything else

    My wife and I also got their Citi card for the cash back on gas, it's worth it. I believe Sam's Club has a similar card offer for their members.

    Great information, guys - thanks! Looking for more usable bonus options than my flight points cards now that we are traveling much less.
    Annual fee$ on those or not?

    For sure. Are Tires/Lift/Towing causing that mpg hit? I see 2-3 mpg more on mine, but it’s still a fairly stock 4WD SR5.

    No annual fees - just your membership fee iirc

    35s with an OME lift on 18" FN BFDs - no towing. 90% of my miles are commuting/around town. Last time I took her on the highway I was getting ~16 mpg (depending on whether I was mostly in mountains or flats). Will be gearing next year (fingers crossed) to help on the local mileage among other reasons.

    Correct, no annual fees for the Citi card, just Costco membership fee.

    Membership fee is $60 for the regular membership and $120 for the executive membership. The executive membership gives you 2% back on Costco purchases minus a few items like alcohol, gas and pharmacy. What I'm not sure on is if you double up on that 2% back if you have the executive membership and Citi card since they both give 2% back on Costco purchases.

    you totally do - the cash back from Citi and from Costco is separate (two separate "checks") and you get both - it's pretty nice.
